Biological Interactions in Rat Tibial Osteogenesis: Micro-CT, Histomorphometric, and Histological Analyses of Bioglass, Fibrin Biopolymer, and Photobiomodulation

What the authors concluded

PBM did not demonstrate a positive effect on bone regeneration at the 42-day time point under the parameters used in this study

Devices that emit this wavelength

Matched on wavelength within 15nm, since LED bins vary by roughly that much and a tighter match would be false precision. Where we have an irradiance figure, the session length is the time needed to reach this study's dose of 30.49 J/cm² at that intensity.

Matching a wavelength is not the same as reproducing a trial. Session times assume the device's published irradiance is accurate at the distance it was measured, which on brand-claim figures is often optimistic. Where a device publishes both a peak and an average we use the average, and where it publishes a falloff curve we use the lowest figure, so these times run long rather than short. Clinical protocols also control for spot size, contact and skin type in ways a home device cannot.
